Abstract
A synapse expressing unit includes a capacitor for storing a synapse load value information in a form of electric charges, and a refresh control circuit for remedying the change in the amount of the electric charges stored in the capacitor. The refresh control circuit includes a comparator for comparing a potential at an electrode of the capacitor and a reference potential, and a drive circuit responsive to the comparator for recovering the electric charges of the capacitor through charge pumping operation. The synapse load value information is refreshed, and therefore a neural network circuit device reliably operating for a long time duration is provided.
